azsecrets: A CLI to Set Azure Key Vault as Environment Variables
Using environment variables to store your secrets is one of the more natural way to do; these variables then can be used in your code throughout the life cycle of your Docker environment. You shouldn’t hard code your secret keys inside your application; it is just not secured. Docker lets you add the environment variable before creating an image or at the entry point when starting up your image,
azsecrets lets you set these environment variables that are stored in Azure Key Vault.
I have borrowed the idea from
docker-machine env CLI command, that spits out several environment variables that it needs to connect Docker CLI to a virtual machine;
azsecrets does that for you.
This package can also be used as a module in your current code if you don’t want to use it as a CLI.
The CLI is written in Python 3 and is available in PyPi at https://pypi.org/project/azsecrets/. To install it open your CMD/Terminal/Powershell and type in
pip install azsecrets
There are two ways to use
azsecrets: as a CLI or as a package
Once you have installed the tool, you will have to set four environment variables (or give it as an argument in CLI) that Azure uses to access Key Vault.
AZURE_VAULT_BASE_URL=*** AZURE_CLIENT_ID=*** AZURE_SECRET_KEY=*** AZURE_TENANT_ID=***
You can then open CMD/Terminal/Powershell and type in
secrets env --shell bash # export VAR-1=secret1 # export VAR-2=secret2
or via CLI
secrets --vault-base-url *** --client-id *** --secret *** --tenant *** env --shell bash # export VAR-1=secret1 # export VAR-2=secret2
secrets --help will give you more information on the usage.
(base) akshayrajgollahalli:~ : secrets --help Usage: secrets [OPTIONS] COMMAND [ARGS]... Options: --version Show version and exit. --vault-base-url TEXT Azure KeyVault base URL. Defaults to None. --client-id TEXT Azure KeyVault client ID. --secret TEXT Azure KeyVault secret. --tenant TEXT Azure tenant ID. --help Show this message and exit. Commands: env Environment configuration: [powershell, cmd or bash].
You can also use
azsecrets as a package by just importing the object to your existing Python code; for example, in Django, you can set your secrets by doing (this example assumes that you have already set the four environment variables):
from azsecrets import AzureSecrets # You can also set the four environment variables or pass the arguments through the object az_secrets = AzureSecrets() SECRET_KEY = az_secrets.get_secret("DJANGO-SECRET-KEY")
